Steps to repair the backlight on Eagle Spectrum Metal Detectors.
1. First buy one of these http://www.ebay.co.uk/itm/A6-EL-Shee...item2edb5f2c54
2. Now remove the LCD and PCB from the machine as normal
3. CAREFULLY unsolder the backlight connections from the LCD PCB
4. Even more CAREFULLY, slide a 6inch steel rule UNDER the backlight EL element starting with the end furthest from the terminals, be VERY careful NOT to put any upward pressure on the display or you will crack the LCD screen.
5. Slowly pull the steel rule out and the EL element should come out with it
6. Take the item you bought in 1 and cut to size using SHARP scissors or “Stanley” knife making sure that ONLY two terminals are in the narrow end (so it looks like the EL part you removed).
7. Reconnect the Display module WITHOUT the EL element and check that the EL inverter “whistles” when BACKLIGHT is set to “6”.
8. Switch off and disconnect display module, now slide the EL element you cut out under the LCD module.
9. Apply a SMALL quantity of plumbers FLUX (needs to be quite aggressive flux) to the terminals and tin as normal
10. Bend and solder to the LCD PCB
11. Reassemble and test. All should be well
Total cost of this repair is around £8.00 for the EL card (you can get two out of each, 4 if you think about the cuts. And half hour of work time.
DETECTOR FIXED and you can have ANJY colour you choose. OH, don’t forget to adjust the display contrast for better legibility than the standard EL unit.
